Hereinafter, a control method of the thermo-hygrostat using the graphic of the present invention will be described in detail with reference to the accompanying drawings.

First, the structure of the control box 2 in which the method of the present invention is performed will be described with reference to FIG. 2. As shown, the control box 2 has a program ROM 20 in which a program for operating the thermo-hygrostat is stored therein, an MPU 21 for controlling the entire stroke of the thermo-hygrostat 1, and a power supply. Four key signals for data input and power supply 22 and display operation status and input / output data (temperature, humidity, set temperature, set humidity, etc.) of each device included in the thermo-hygrostat 1 Is connected to the LCD panel monitor 23 in which a keypad control unit (4key pad control) is input, a control output module 24 for outputting a control signal, and the control output module 24 to turn on / off specific devices. A control output unit 28 for turning off, a signal input unit 29 connected to the devices for receiving status data of specific devices, and an alarm input module for interfacing a signal input from the signal input unit 29 ( 25), temperature and humidity sensors (26), It can be seen that the communication port 27 for communication with a computer or R.M.U.

Inside the MPU 21, an EEPROM area, a serial communication area, and an A / D converter (8 bits) are built in, and perform their respective roles. In other words, the EEPROM area temporarily stores data input through the temperature and humidity sensor 26 (8-bit) and modulated by the A / D converter. The EEPROM area does not need to have a large capacity because it temporarily stores data. It is desirable to have a capacity of about 128 bytes. In addition, the serial communication area is connected to the communication port 27 for communication with the outside to exchange data. The MPU 21 can be configured using, for example, a one-chip microcomputer having the above functions.

The control output unit 28 serves to supply power to operate a specific device (blower drive motor, heater, humidifier, evaporator) and the like by the signal from the control output module 24. For this purpose, a plurality of solid state relays (S.S.R: solid state relay) 28a, etc. are installed in the control output unit 28, and it can be seen that 14 solid-point relays 28a are shown in the drawing. Of course, it will be apparent to those skilled in the art that the number of contactless relays thereof can be increased or decreased as needed.

In addition, the signal input unit 29 connected to the alarm input module 25 is provided with a plurality of isolators 29a for receiving a signal input from a specific device or the like. The signal input through the signal input unit 29 becomes a state signal of specific devices and is later stored in the MPU 21.

The method of the present invention to control the thermo-hygrostat is performed in the control box 2 of the thermo-hygrostat 1 as described above, which will be described below with reference to the accompanying drawings.

The method of the present invention includes a first step of displaying and waiting each component of the thermo-hygrostat and the operating state such as the current temperature and humidity when the power is supplied and the operation command is input in a corresponding graphic state; A second step of outputting a specific menu of the main menus displayed as "setting", "recording", "alarm" and "stop / start" when the user inputs a menu setting input; A third step of displaying a graphic enlargement of the graphic when the "setting" menu of the main menu is selected by the selection input signal and graphically displaying numerical data changed by the up / down signal input; When the “Record” menu is selected in the main menu by the selected input signal, it is enlarged graphically and the left / right movement command is input to display the time change status of the temperature and humidity graph graphically. A fourth step of returning; When the "Alarm" selection signal in the main menu is input by the selection input signal, the status display of each component of the thermo-hygrostat is displayed graphically, and the status of the components is sequentially displayed and returned according to the page up / down command signal. A fifth step of returning to the main menu when a command is input; And a sixth step of displaying the graphic enlarged when the "stop / start" menu is selected by the selection input signal and cutting off the power supply or displaying the test / setup mode graphically when a specific signal is input. .

When power is first supplied to the thermo-hygrostat 1 and the operation mode is started, the screen as shown in FIG. 4 is output to the LCD panel monitor 23 of the control box 2. The screen displays operating status such as temperature (20.0 ℃), humidity (49.5%), cool, dehumidification (Dehu), heating (Heat) and humidity (Humi). Four menus of "Setting", "Record", "Alarm", and "Stop" are displayed. At the bottom, four keys (s1, s2, s3, s4) (push buttons) for inputting a command are provided. Specific devices are displayed graphically, indicating that each component, compressor, evaporator, heater, blower, etc. is operating flashing in the graphic state.

In this state, if the user wants to set the temperature, the menu screen can be activated by pressing the key s1 connected to the bottom of the "setting" menu. FIG. 5 illustrates a screen for setting a temperature by pressing the “setting” menu once, and it can be seen that the setting temperature is set to 20.0 ° C. FIG. To raise or lower the temperature, the user can adjust the pressure by pressing the assigned keys (s2, s3) at the bottom of the "up" and "down" menus.

It is apparent to those skilled in the art that the present invention can be configured to press the "up" key once to increase by one degree Celsius, and to press the "down" key once to decrease by one degree. In addition, it is possible to limit the upper limit temperature (30 ℃), the lower limit temperature (10 ℃) for the operational stability of the thermo-hygrostat. That is, the upper and lower limits of the temperature can be fixed according to the characteristics of the place where the thermo-hygrostat is installed.

After the temperature setting is completed, press the key (s1) again in the "Setting" menu to select "Responsive Temperature" and another menu is displayed on the "Set Temperature" menu in the form of a rectangle as shown in FIG. Range is displayed. The "sensitization temperature" is for adjusting the variable range of temperature, for example, the upper limit temperature may be set to 5 ° C, and the lower limit temperature to 0.5 ° C. That is, it is possible to adjust the temperature up and down sequentially in the temperature range set by the "sensing temperature" when adjusting the set temperature, which can be seen that fine adjustment is possible by reducing the numerical value.

In addition, when the "setting humidity" is selected by pressing the key (s1) in the "setting" menu, the "setting humidity" screen is displayed on the screen of the LCD liquid crystal monitor 23 as shown in FIG. The user can set the humidity again using the keys s2 and s3 (push buttons) for inputting the "up" and "down" signals displayed at the bottom. In other words, you can adjust the humidity by pressing the key installed on the lower side with "Set Humidity" displayed. At this time, the upper and lower humidity can be set to 65% and the lower limit to 35%. Also, the "Humidity" can be set at 10%, The lower limit humidity can be set to 1% by pressing the "up" and "down" keys, respectively. The settings of "set temperature", "response temperature", "set humidity", and "sensitized humidity" can be adjusted by continuously activating them by pressing the first key in the "Selection" menu. This is shown in detail in FIG. 8.

When this adjustment is completed, the user saves the changed setting data by pressing the key s1 in the "save" menu as shown in FIG. The changed data are stored in the MPU 21 and maintained until a change command is input again. Alternatively, if you want to end this while setting the temperature and humidity, press the "Stop" menu in any state to exit without changing the data.

The "Selection" menu also allows you to specify a "communication number" for data communication with other computers or R.M.U. The " communication number " is activated to allow connection by designating a " communication number " after assigning a number to a computer or R.M.U connected in advance through the communication port 27. This can be used to control the thermo-hygrostat 1 externally or remotely. That is, the result of measuring the temperature / humidity of the place where the thermo-hygrostat 1 is installed is to be sent to a computer or R.M.U, and to transmit a control command from the computer or R.M.U. This is shown in FIG. 9 and the "communication number" can be set to, for example, the upper limit number 20 and the lower limit number 0, which limits the number of computers or R.M.U.

When the "Record" menu is selected in the initial "Selection" menu (see Fig. 4), the state of change of temperature and humidity is displayed in a time graph. Shown in FIG. 10 is a graph showing a temperature changed during a predetermined time. As shown, it can be seen that the temperature decreases as time passes to maintain a constant temperature (set temperature) and the humidity continues to maintain a constant value.

In addition, it is possible to move by time zone by the “left / right” menu indicated by an arrow. That is, the graph moves to the left side by pressing the "left" menu using the key s2 as shown in FIG. By doing this, the change in temperature and humidity can be known for more time. It will be appreciated that the position of the temperature and humidity can be changed up and down. The temperature and humidity change data are values that are modulated and stored in an 8-bit A / D converter of the MPU 21 after being input through the temperature and humidity sensor 26. This is stored in the internal memory element of the MPU 21 for a predetermined time (for example, for 1 minute, 10 minutes or 1 hour), and is outputted when the "record" menu is selected. When the "return" menu is pressed while the temperature and humidity are output, the display returns to the main menu as shown in FIG.

When the "Alarm" menu is selected from the "Main" menu, an alarm record is output to the LCD panel monitor 23 as shown in FIG. The alarm records are recorded alarm conditions generated in the devices included in the thermo-hygrostat 1, and these are input through the alarm input module (25 in FIG. 2). A plurality of isolators 29a are connected to the alarm input module 25, and each of the isolators 29a has an AC24V input including a status signal from each device (blower, compressor, heater, humidifier, etc.). Is entered.

Of course, it will be apparent to those skilled in the art that the number of isolators can be increased with increasing number of devices for controlling. The input signal is finally converted by the 8-bit A / D converter and stored in the MPU 21. The data output as the alarm record is thus displayed as normal or abnormal status as data stored in the MPU 21.

While the alarm record is outputted, the "Return", "Recovery", "Record", and "Stop" menus are displayed on the lower side. Press the key on the lower side to select the "Return" menu and return to the "Main" menu to maintain the standby state. When the "Record" menu is selected it will display the history of each device. In other words, the operation status of when and when each device is up to date is displayed. In this state, when the user selects the "erase" menu by pressing the key s2 as shown in FIG. 13, the data of the inverted state is deleted and when the "down" menu is selected, the page is sequentially down and the entire data is displayed. .

14 shows a state in which the final data is displayed, and since no more data exists, it can be seen that the lower side is displayed as an empty space. In addition, instead of the "down" menu, the "up" menu is displayed so that data can be displayed. At this time, if the "return" menu is selected in the state shown in FIG. 14, the first recorded data is displayed again as shown in FIG. The displayed recording data can be changed according to the size of the memory, and in the present invention, about 32 cases can be displayed over two pages.

When the "Stop / Run" menu is selected in the initial "Main" menu, a screen as shown in FIG. 15 is displayed on the LCD panel monitor 23. This is to set the initial operation value of each device, and the temperature and humidity value from the sensors, the driving power of each device, the driving state, etc. are displayed. In addition, "Selection", "Selection", "Start", and "Stop" menus are displayed at the bottom. The user can adjust the operation state after selecting by using the keys s1 and s2 indicated by arrows set upward and downward.

Fig. 16 shows that the system is stopped (down) after about 45 seconds when the stationary state is selected. The thermo-hygrostat (1) automatically shuts down after 45 seconds unless a new command is input. This time can be set for safety, because the operation of the thermo-hygrostat directly affects the room.

When it is completely stopped, the operation of the thermo-hygrostat 1 is stopped and the logo of the standby state is displayed as shown in FIG. In this state, press the key (s4) for power on, the operation starts and the screen shown in Figure 4 is displayed while the thermo-hygrostat is operated and waits for command input.

According to the present invention as described above has the advantage that the user can easily recognize and input the control data by outputting the operating state output and the control data input of each device connected to the thermo-hygrostat.

Although the invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that modifications and variations can be made within the spirit and scope of the invention, and such variations or modifications will belong to the appended claims. .
